Installation
 Location
• Hot water module is allowed to install indoors.
• Avoid installing near machines emitting high frequency waves.
• Not suitable for chemical plants such as liquefied carbon dioxide refrigerant plants.
• Do not install the hot water module in locations where iron or other metal dust is present. If iron or other metal
dust adheres to or collects on the interior of the hot water module, it may spontaneously combust and start a fire.
• A failure may occur in certain locations such as the following:
• Areas with large amount of oil droplets (including machine oil) or vapors
• Salty areas near oceans, etc.
• Hot springs emitting sulfidizing gas, etc.
• Heavily acidic or alkaline places.
Special maintenance or parts are required for use in the above places. For details, contact the dealer where you
purchased the product.
• Leave an enough space around the air intake and discharge of the outdoor unit so that the ventilation is not
restricted.
• Avoid places where strong wind may blow against the air intake and discharge of the outdoor unit.
• Attach a snow stand, snow hood, etc. to the outdoor unit for use in snowfall areas. For details, contact the dealer
where you purchased the product.
• Make sure drain water from the outdoor unit and the hot water module are emitted into places with good
drainage.
• Keep a distance of at least 1 m between the hot water module / remote controller and a TV or radio. Failure to
observe this precaution may cause visual disturbance or noise.
• Leave a distance of at least 1.5 m between the hot water module and a fire alarm. If this precaution is not
observed, the alarm may not work properly or detect fire in case of fire.

Be careful of operation sounds
• Locate the unit in a place secure enough so that the sounds and vibrations do not increase.
• If something is placed near the air discharge of the outdoor unit, noise may increase.
• Be careful not to disturb your neighbors with cool / heat air or noise coming from the air discharge of the outdoor
unit.

Notes on operations and performance
 Check before operation
• Turn on the power switch at least 12 hours before
starting operation.
• Make sure the earth wire is securely connected.
 Defrosting during heating
• If frost falls on the outdoor unit during heating,
defrosting is automatically performed (for
approximately 2 - 10 minutes) to increase the
heating effect.
• The Hot water module keeps operating the pump
during defrosting.
• The hot water module stops the compressor
operation during defrosting.
(For High temperature Hot water module type.)
 3-minute protection
The outdoor unit will not operate for approximately 3
minutes after the air conditioner (including hot water
module) has been immediately restarted after
stopping, or the power switch has been turned on. This
is to protect the system.
 Power failure
• In the case of a power failure, all operations stop.
• To resume operations, push the ON/OFF button.
 Protective device
(High pressure switch)
The high pressure switch stops the air conditioner
(including hot water module) automatically when
excessive load is applied to the air conditioner system.
If the protective device activates, the unit’s running
stops and the operation lamp blinks.
When the protective device activates, the
indicator
and the check code are displayed on the remote
controller.
The protective device may activate in the following
cases:
During cooling
• When the air intake or air discharge of the outdoor
unit is blocked.
• When strong wind blows continuously against the air
discharge of the outdoor unit.
During heating
• When dust or dirt is excessively adhered to the
strainer (locally procured) of water pipe.
• When the water flow rate is lower.
NOTE
When the protective device activates, turn off the
power switch, remove the cause, and then restart
running.
 Cooling / Heating operations
<Heat pump>
Each unit can be controlled individually. However,
indoor units connected to the same outdoor unit cannot
perform cooling and heating simultaneously.
When you attempt simultaneous operation, hot water
module performing heating are stopped, and the
running preparation indicator
is displayed on the
remote controller.
An indoor unit performing cooling continues running.
When you attempt an operation without the configured
settings, the running preparation indicator
is
displayed on the remote controller and operation stops.
If operation is fixed to cooling or heating by the air
conditioner administrator, only the configured settings
apply to the operation.
